No, you can not make roux in a crock pot. Roux is not a gravy, a sauce, or anything else of the sort. Roux is the base of many sauces & gravies not only in French cooking but Cajun cooking as well. You can make a roux gravy or a roux sauce, the roux itself can not be made in a crock pot.
To make roux you need equal parts oil (a fat) and flour (all purpose is best).
Heat oil in a skillet (frying pan) when oil is warm, close to hot frying stage but not overheated, slowly mix the flour. Continue cooking the oil and flour mixture over medium heat stirring constantly. Cooking times vary, depending on the type of gravy or sauce you desire. 2-3 minutes will produce a very light colored roux, recommended for a milk based gravy/sauce. The longer you cook the roux the darker it will become. Be careful, not only does the oil/flour mixture become very HOT it can burn very easily, constant stirring is a MUST.
I have to add, the best flavored roux is made with butter. The amounts are the same, however, melt the butter before measuring. For example if 1 cup flour & 1 cup "melted" butter.
Also stir the flour into the butter or oil (whichever you are using) as it heats, if you allow the fat to get too hot before adding the flour, the flour will actually fry and develop lumps. Add the flour slowly stirring constantly to ensure proper mixture. The flour will make the fat thick and heat up along with the fat and begin to darken.
You will seal the top of the crock pot with a flour paste called "lute". See related links for instructions.
